I am also looking for a Linux version.

 Not a lot of point to a LINUX version right now, since there are ZERO WORKING LINUX DRIVERS for the Vega.


I'm no longer legendary just in my own mind!

WOOT - got all 6 so far working.  Thanks fellas i had some dumb crap going on.  FYI Pagefile is 45G and it works like a champ on 6.  30-35 it crashed.  6 so far at 12K hash, tomorrow i go for the 7th!

what drivers are you using to get 6 running?

it would be nice if in the next versions fix the problem with a falling hash rate on one of the cards in the console

congrats! for those who have 6 or more Vega 56 cards...how do you plug them all to the PSU taking into account that every Vega takes up 2 VGA power supply slots? I have 6 Vega 56 but two are just unplugged because my 2 750W PSUs don't have more than 4 VGA 8 pin inputs

You can sell one Vega and buy very good PSU for its price. Moreover, selling price will be much higher than you bought it because of out of stock and crazy hype ))

haha, thanks for the suggestion!! In fact I have 4 Vega 56 doing nothing, just 2 of them are working. 4 are plugged (2 for each PSU) but my second PSU doesn't work because it's not connected to the ATX 24 pin port of the MOBO. Newbie life....now I need a 2 to 1 24 pin ATX connector, to plug both PSUs to the MOBO.

Have you ever tried doing a softpowerplaymod with those settings?  Did it work?  Whenever I try settings like that, card refuses to boot, or P states "disappear".

The Lepa 1600 has 12 ports, well 6 split to 12 but right at PSU.

The EVGA 1600 has 9 ports (this one is better)

Get those for good results.  Fuck linking little shit together.

how do i solve the falling hash rate problem? Seems like the hashrate keeps going down after mining for a while.

what type are your PSU? Use 2 corsair 1000w, or even 2x 850. They come with double 8pin cables and you have enough to run all 6.

it would be nice if in the next versions fix the problem with a falling hash rate on one of the cards in the console
That's usually more of an issue with one of your GPUs. It would be nice if the program could continue without crashing when one card drops off, but there's an equal chance that's a driver/Windows issue vs a Cast issue.

Not a lot of point to a LINUX version right now, since there are ZERO WORKING LINUX DRIVERS for the Vega.
You mean these? Granted, they aren't as performant as the Windows drivers, especially since I don't think there's a way to set the clock/voltage rates as easily, but the drivers do indeed exist.

I learned about this miner just today, also learned about the amd blockchain driver today too Smiley (I was using nicehash so ... never bothered before :/ ) The thing is I am getting 700h with rx480 with normal amd driver. I wanted to ask if I'll get additional performance if I use the specific driver or is this the best this card got. (I am also getting 700 with 9.7 claymore)

Hi,

Great miner.

Is there a way to create a logfile as i don't see any switch etc to do this. I have monitoring setup with Zabbix and I would like to pull data from the logfile to be displayed in Zabbix.

thank you

Hello,

i got the following issue:

initially i got average around 1900h/s and after some time, it can be minutes or hours, i drops to 1500-1600h/s

Anyone having such issue and eventually a solution ?

I'm experiencing the same Sad. No ideea how to fix it

Visit vegamining blog authored by @Circusdad.  This issue is discussed and a script for XMR-STAK to monitor hash rate and restart is provided; a few posts back in this thread, user StellarX88 explained how to modify that script to work with Cast.  Meaning, once you customize the script as laid out, and based on the number of cards that you have, the script will restart Cast if your hash rates drops below the hash limit that you define.  Not foolproof, but it has been working fairly well.

If your hash rate is dropping every few minutes, then your problem is with bad values for P7 and P3 (OverDriveNTool), or too aggressive settings in XMR-STAK config file.

Thanks for the pointer!

In my case , seems I'm a bit lucky. I actually get hash drops when monitor goes to standby mode. So switching it to always on cured almost everything.

What does that script do? Is it smarter than parsing the console? I could create one myself rather than modyfing an existing one which might be more complicated.
In case I'll need it one day

I dont know why, if i using this mining software with Amd RX 570 and mine Electroneum at pool always say " Not Connecting to pool / failed connect to pool" using port 5555 3333 and https secure 443 is same problem, but if i change to monero pool at nanopool, this software can connect to pool and give high hashrate for my card
About 800 - 850 H/s per card
Any have same issue with me?

Ok, here is the input
if I'm using the cast miner initially I have better hashrate from the very beginning - like 1962 on my vega ( on xmr I have 1942)
but after 5-10 minutes it slowly began to decrease, while using xmr it is stable
will till now I have no solution to this
I have some ideas, will check and report back

WOOT - got all 6 so far working.  Thanks fellas i had some dumb crap going on.  FYI Pagefile is 45G and it works like a champ on 6.  30-35 it crashed.  6 so far at 12K hash, tomorrow i go for the 7th!


congrats! for those who have 6 or more Vega 56 cards...how do you plug them all to the PSU taking into account that every Vega takes up 2 VGA power supply slots? I have 6 Vega 56 but two are just unplugged because my 2 750W PSUs don't have more than 4 VGA 8 pin inputs

The Lepa 1600 has 12 ports, well 6 split to 12 but right at PSU.

The EVGA 1600 has 9 ports (this one is better)

thanks for the tip! Gotta decide which one should I get..

what type are your PSU? Use 2 corsair 1000w, or even 2x 850. They come with double 8pin cables and you have enough to run all 6.

it is a EVGA 750W 80Gold.

Talking of which, I am not sure if I should connect a 3rd Vega to the 750W PSU, I am fearful something get fried because mining consumption seems fine at 150W but my fear comes from the fact that I don't want it to peak because of...whatever and things get out of hand for the PSU

Hі, guys,  Cаst XMR  mаx wоrk wіth 4 Vеgа's?  Аrе thеrе lіmіtаtіоns ?  Thаnks
I think it can work with up to 8 or more,afaik? It also depends on the AMD drivers.

how do i solve the falling hash rate problem? Seems like the hashrate keeps going down after mining for a while.
do you use a iGPU? If so, connect a headless HDMI ghost so your computer thinks there is a monitor connected all the time.

I enabled the iGPU (the integrated GPU of your mobo or Intel processor) in the bios settings as the main graphics device and the Vega never drop a single hash the entire time.

Also, I am not using AMD Wattman (only the Blockchain august drivers) but these settings, in a bat, that launch with Windows -so does Cast XMR- with OverdriveNTool work fine for me (stable 1970H/s+):
